# Algorand - The Undocumented Docs



Dev Notes for Archival Node, Indexer Setup (and more)



## Archival Node FAQ



### [ ? ] How much space will I need?



See -> https://howbigisalgorand.com/



### [ ? ] How long will it take to stand up an Archival Node?



Depends on hardware. The biggest bottleneck is I/O speed. NVMe is by far the optimal HW for this purpose. If you plan to run both an Indexer and Archival Node, split their data directories on separate drives. Some representative hardware estimates (as of block # 18,400,000):



- Raspberry Pi 4 - Archival Node - 11 days



### [ ? ] My archival node started off wicked fast and now it is slow as molasses. (Usually around block 8M+) Why?



Reportedly this was due to an Italian company minting millions of Assets/NFTs, regardless Algorand began seeing much greater popularity around this point. Expect a long, hard slog after block 8M.



![Transaction History](https://media.discordapp.net/attachments/807825288666939482/926325259311919145/unknown.png "Transaction History")



### [ ? ] How do I figure out what relays I'm connecting to?



On Linux: `netstat -nap | grep algod` (port 4160 for MainNet)



### [ ? ] What are the `LookupSRV` errors in `node.log`?



Set `"EnableBlockServiceFallbackToArchiver": false` in your `$ALGORAND_DATA_DIR/config.json` to get rid of these



## Indexer FAQ



### [ ? ] Can the Indexer be set at a specific catchpoint to ignore prior blocks?



Not currently. If your use-cases differ, you may want to consider forking the Indexer or writing your own direct interface to `algod` and skipping the Indexer



### [ ? ] How long for the Indexer to fully catch up?



ETA currently unknown. Please pull-req if you have estimates.
